2 Claims.

This invention relates to a mop pail; and has special reference to animproved wringer device secured to the top of the pail for wringingexcess water from a mop during withdrawal thereof from the water withinthe pail.

An object of the invention is to provide an improved mop wringer pailcomprising a rigid frame wholly enclosed within and rigidly attached tothe inside of said pail for supporting one of the wringer rollers at theopen upper end of the pail, in combination with a frame pivoted to saidrigid frame inside the pail for swinging movements and supporting theother one of the two cooperating rollers, a lever attached to saidswinging frame inside the pail beyond its axial support from the rollersupported thereby and extending above the pail to a position forengagement by the foot of the user to operate said swinging frame, and aplatform or foot-rest attached to said swinging frame for receivingpressure to hold the roller supported by said swinging frame incooperative relation with the roller mounted on the rigid frame.

Other objects and advantages of the invention will be apparent from thefollowing description, reference being made to the annexed drawing, inwhich- Fig. 1 is a perspective View of the invention applied to a moppail.

Fig. 2 is an enlarged vertical sectional view of my improved mopwringer.

Fig. 3 is a plan view of a portion of the device showing the means forpreventing the mop from becoming entangled with the roller supports.

The pail I may be of any appropriate form and dimensions having a closedbottom and an open top. An ear 2 is rigidly secured to each of twoopposite sides of the pail I, and a bail 3 has its ends pivoted to saidears and may be provided with a rotary handle 4. Ihe bail 3 is of suchsize that it may swing from downwardly inclined position at either sideof the pail upwardly to vertical position to support the pail. As shownin Fig. l, the bail 3 is in an intermediate position from which it maybe swung either upwardly or downwardly.

The frame of my improved mop Wringer is rigidly secured within the upperportion of the pail. Said frame comprises two side members 5 connectedat one end by an arcuate portion 6 and having arcuate portions 'l attheir opposite ends. The portions 6 and 'I seat against the innersurface of the upper margin of the pail and are rigidly attachedthereto, thereby supporting the frame side members 5. Thus, the frameparts 6 and 'l reinforce and strengthen the upper margin of the pail andalso support the wringer mechanism in connection therewith.

A pair of combined guards and roller supporting brackets are lattachedto the frame side mem- -bers 5. Each bracket is preferably composed ofsheet metal and includes a part 8 attached to the frame side member 5and having at its forward end an upwardly extended portion 9constituting a bearing for the adjacent end of the roller supporting rodI0 on which the roller II is mounted. The rod I Il may be rigid with theroller II or not, as desired. The ends of the roller II are adjacent tothe bracket portion 8 -which prevents substantial longitudinal movementoi the roller. An inwardly extended triangular portion I2 is formed inconnection with the lower edge of each bracketportion 8 and issubstantially below the lower periphery of the roller II. A guard wallI3 is formed integral with the lower edge of each flange I2' adjacent toand rearwardly from the roller II. The walls I3 at opposite sidesdiverge rearwardly from each other as shown in Fig. 3, the rear ends ofsaid walls being adjacent to the frame side members 5.

A swinging frame comprising a cross member I4 and two forwardly extendedarms I5 is pivoted upon an axial support I6 mounted in connection withthe opposite ends of the frame side members 5 from the roller axle II).The roller axle I0 and the rod I6 are parallel with each other. A rolleraxle I'I is mounted in the forward ends of the arms I5 parallel with theroller axle I0 and supports a roller I8 preferably of about the samedimensions as the roller II. A foot lever I9 is attached to the crosspart I4 approximately at the middle thereof and is of such a length thatit may swing downwardly at the inner `side oi the curved frame part 6 soas to permit the swinging frame to be moved from the position shown insolid lines to the position shown in broken lines in Fig. 2'. In thesolid line position, the roller I8 is Iagainst the roller II andsupported thereby; and, in the broken line position, the roller I8 isrearwardly beyond the center of gravity so that the swinging frame willremain in an upwardly and rearwardly inclined position until positivelymoved in the opposite direction beyond the center of gravity.

A foot-rest comprising a knurled or corrugated base 2D, a downwardlyextended rear ilange 2l, an upwardly extended front ange or guard 22,vand downwardly extended end portions 23, is rigidly attache-d to thearms I5 of the swinging frame. As shown, the end portions 23 of thefoot-rest are rigidly attached to the outer sides of the arms I5, theflange 2| engages against the upper edges of said arms I5, and theflange or guard 22 rises from the forward edge of :the footrest 20 ashort distance rearwardly beyond the roller I B. The foot-rest 20 isapproximately horizontal when the roller I8 is against the roller II.The formation of the foot-rest with the end flanges 23, the reardownwardly extended flange 2 I and the opposite upwardly extended ilange22, provides a rigid connection between the arms I5 and holds said armsin rigid relationship with each other.

The device is used by applying pressure of one foot `against the leverI9 to move the swinging frame from the solid line position to the brokenline position, leaving an opening between the rollers II and I8 throughwhich the mop may be passed into fthe pail. After the mop has beenpassed into the pail, the swinging frame is moved forwardly to place theroller I8 against the upper side of the mop. Then pressure is appliedupon the foot-rest 20 and the mop is withdrawn between the two rollers,which wring or press excess water from the mop. The guards I3 preventthe mop from becoming entangled at the ends of the rollers I I and I 8.

This invention attains all of its intended objects and purposesefciently, economically and satisfactorily, and dispenses with the useof piv u oted lever connections or other mechanism attached to theoutside of the pail. The structure is strong and durable and willwithstand all of tions; a roller supported by said side portions forrotation about a horizontal axis partially within the upper end of thepail; a pair of arms pivotally supported by said side portions withinand near the opposite side of the pail from said roller and connected bya base member; a second roller rotatively supported by said arms about ahorizontal axis parallel with the axis of said rst roller; and a footlever attached to said base member between said side portions andinwardly from the adjacent curved portion of said frame and extendingupwardly above the upper end of the pail for swinging movementsdownwardly within the pail to move said arms and thereby said secondroller upwardly away from said lirst roller.

2. In a mop pail having an open top; a frame including two oppositecurved portions tting against and rigidly attached to the inner surfaceof the upper margin of the pail, and two approximately parallel sidemembers rigidly connecting said curved portions; a roller supported bysaid side portions for rotation about a horizontal axis near one of saidcurved portions; guard elements attached to said side members within thepail and converging from said side members toward said roller ltoprevent mop material from becoming entangled at the ends of said roller;a pair of arms pivotally supported by said side portions near theopposite side of the pail; a second roller rotatively supported by saidarms about an axis parallel with the aXis of Said first roller; a partrigidly connecting said arms adjacent to the pivots supporting them; afoot lever attached to said part and extending upwardly above the upperend of the pail for swinging movements downwardly within the pailbetween said part and the adjacent curved portion of said frame to movesaidmarms and thereby said second roller upwardly away from said rstroller; and a bail pivoted to lthe opposite sides of said pail forupward and downward swinging movements when said rollers are in contactwith each other.
